Video: Adam Ondra Climbs Silence, The Hardest Route in the World

Adam Ondra is one of the best rock climbers in the entire world, putting up impressive routes on a regular basis. But none are more impressive than Silence, the climb he completed last fall in a cave in Norway. This route was later rated a 9c (5.15d), making it the hardest graded climb anywhere in the world. The video below gives us a glimpse of that climb and takes us through Ondra's obsession with completing it. When it comes to climbing it doesn't get much better than this. Amazing stuff indeed.
